Answer this question truthfully
### Question: What causes Necrotising enterocolitis?
### Response: Necrotizing enterocolitis occurs when the lining of the intestinal wall dies and the tissue falls off. The cause for this disorder is unknown. However, it is thought that a decrease in blood flow to the bowel keeps the bowel from producing mucus that protects the gastrointestinal tract. Bacteria in the intestine may also be a cause.
This disorder usually develops in an infant that is already ill or premature, and most often develops while the infant is still in the hospital.
